Clen and Sports

Hey guys. I am varsity athlete at the collegiate level. I was just wondering if taking clen and participating in a sport would be hazardous? I have done a lot of reading on clen. and are familiar with what it does and its sides. I just wanted to get some feedback from those who have used it while participating in intense activities.

I know athletes are told not to take ephedra (which I am sure many of you might disagree with) but I was wondering how an ECA stack differed from clen and if you guys think it would ok for me to take? Thanks so much for your time.
